Which option must be selected to create a form that organizes entries in a datasheet subform?

To create a form that organizes entries in a datasheet subform, selecting a table, such as the one named "Departments," is essential. This is because a form needs underlying data to display, and tables are structured collections of related data that form the backbone of your database.

When a subform is created, it often pulls data directly from a related table to present dynamic information that corresponds to the main form. For instance, if your main form shows information about a company or a particular project, the subform could show all the associated departments, which are stored in the "Departments" table.

Utilizing the field list merely provides access to the fields from the underlying tables or queries but does not structure the data into an organized subform format. Queries also serve to process and present data, but they do not provide the direct structural framework like a table does. While form layout concerns the design and arrangement of the form elements, it doesn't address the specific need for structured data organization that a table inherently provides.

Choosing the correct table ensures that the form can effectively represent the data, allowing users to view, enter, or modify information seamlessly as intended within the context of a relational database.
